Who is the real ranger in the lighthouse of the orcas?

In "The Lighthouse of the Orcas" by Julia de Villiers, the real ranger is not a traditional park ranger but rather a dedicated father figure to the orca whales. The story revolves around a bond between a mother and her son who travels to meet this ranger, who has a deep understanding of the orcas and their habitat. The ranger's passion for wildlife and his role in protecting the orcas highlight the themes of love, family, and the connection between humans and nature.
